I've downloaded it to both my iPhone and my iPad 1, and have worked on "staring" those events on the schedule that interest me. It does permit multiple items per hour to be "star"ed. Once you have done this, the items appear on "My Schedule" within the app. I have also been able to manually add non-scheduled events like meet-ups with friends. The list on the iPhone app RootsTech '12 "Dashboard" includes:

My Schedule

Maps

Events (the official schedule)

Speakers

Conference Documents

Photo Gallery

Videos

Twitter

Friends (be sure to make your own profile there)

News

I haven't checked the "syncing" between two devices so I am not sure if it works to make entries on one device that show up later on my other device.
